并列结构作主语以及名词加介词短语作主语
并列结构作主语
并列结构作主语时，谓语动词与最靠近的主语保持一致。如果并列结构是单数形式，谓语动词用单数形式；如果并列结构是复数形式，谓语动词用复数形式。例如：
Both she and her husband are doctor.（她和她的丈夫都是医生。）
John as well as his parents，like sports.（约翰和他的父母都喜欢运动。）
None but two students passed the exam.（除了两个学生外，没有人通过考试。）
Neither在英语中，非谓语动词可以作主语吗？
不可以，非谓语动词在英语中不能作主语。非谓语动词包括动词不定式、动名词和分词，它们在句子中不能作为主语来引导句子。在英语中，主语通常是名词或代词，而不是动词形式。例如，“To eat an apple every day is healthy”这个句子中，“To eat an apple every day”是一个动词不定式作主语，但是它不是一个名词或代词，因此不能作为主语。正确的说法是“Eating an apple every day is healthy”（每天吃一个苹果是健康的）。
由and或both... and连接两个名词、代词作主语，表示不同的人或事物时，句子的谓语用复数。
John and Mike are good friends. 约翰和迈克是好朋友。
Both bread and milk are good for you. 面包和牛奶对你都有好处。
【注意】and连接的两个名词作主语，在意义上指同一人、同一物或同一概念时，谓语动词用单数。
The famous singer and dancer is coming to Chongqing. 那位著名的歌唱家兼舞蹈家要来重庆。

＂名词+介词短语＂作主语
在英语中，"名词+介词短语"可以作为主语，这种结构被称为"名词短语"。
名词短语是由一个名词和一个介词短语组成的，通常用于描述一个人、一个物体或一个概念。这个名词短语可以在句子中作主语、宾语、表语或补足语。
例如：
The problem with internet addiction is becoming increasingly serious.（网络成瘾问题变得越来越严重。）
The population of China is about 1.4 billion.（中国的人口约为14亿。）
The idea of traveling to Mars is fascinating.（去火星旅行的想法很吸引人。）
在这些例子中，"the problem with internet addiction"、"the population of China"和"the idea of traveling to Mars"都是名词短语，它们作为主语引导了整个句子。
名词或代词后接as well as，with，along with，together with，except，but等短语作主语时，谓语动词的形式应和介词短语前的名词或代词的人称和数保持一致。
She as well as other students likes playing computer games. 她和其他学生都喜欢玩电脑游戏。
He with his parents is working in the fields. 他正和他的父母在地里干活。
Nobody but you and me knows it. 除了你和我，没人知道。

1. A【解析】句意：——他们学校里大约四分之三的老师出生于20世纪80年代。——剩下的出生于20世纪70年代。由分数修饰的主语后面谓语动词的数，和被修饰主语的单复数保持一致。剩下的老师是复数概念，故选A。
2. D【解析】句意：除了他和我我们班上的每个人都愿意参加这个活动。根据句意及题干分析第一空作except的宾语，所以用代词的宾格，排除A、B；第二空句子的主语是everyone，except的短语只是作状语，所以此空谓语动词要用is，故选D。
3. A【解析】考查there be 句型。句意：现在是12点。一定有很多人在餐厅吃午饭。There be sb./sth.doing sth. 有……在做某事。故选A。
4. D【解析】考查主谓一致及不定代词的用法。句意：不但这对孪生兄弟，而且他们的表弟吉姆都去过日本，但是他们没有一个会说日语。在英语中，not only...but also...连接两个成分作主语，其谓语动词应与其最近的主语在＂数＂上保持一致。此外，neither表示两者都不，none表示三者或三者以上都不。故选D。
5. D【解析】考查there be句型和介词。句意：5月1日下午将有一个＂援助之手＂会议。在具体某一天的上午或下午，早上用介词on；of ……的，五月一号的下午是the afternoon of May 1；根据时间可知用there be的将来时（there will be/there is(are) going to be）；故选D。
